3 General Description / Application Multi-stage high pressure pumps for water supply, irrigation and industrial applications, for hot and cold water circulation, fire fighting, boiler feed and pressure boosting installations. Suitable for all clean or slightly dirty non-corrosive liquids (e.g. water, oil, etc.) up to a viscosity of 150 mm²/s (cst). Operating range Nominal branch diameter DN Capacity Q up to 550 m 3 /h Head H up to 400 m Operating pressure p up to 40 bar Liquid temperature t -20 C up to +140 C Speed n up to 3600 rpm Product advantages Numerous horizontal and vertical models for an efficient building design. Flexible arrangement of suction- and delivery branch. Numerous hydraulic units per model size guarantee a design at the optimal operating point. High efficiencies, absolutely stable and steep characteristic curve owing to optimized hydraulics. Optimal adaptability to the medium to be pumped owing to a variety of material and sealing versions. Pump shaft protected along its entire length by means of impeller hubs and sleeves. Detachable stuffing box gland simplifies replacement of the packing. Designation Series HP /5/S + 22/4 Fitting of standard mechanical seals instead of gland packing, without additional work on the casing elements. Balancing of the axial thrust by means of balancing piston (at high pressure). Nominal branch diameter [mm] Nominal impeller diameter [mm] Hydraulics ID Number of stages Arrangement Nominal power P2 [kw] Number of poles Example 3

4 Selection chart This chart allows a provisional selection of the pump type most suitable for a given set of operating conditions. In certain cases it may be possible to use the next smaller pump type and this possibility should be included in the final selection. For an exact pump selection our individual characteristic curves as well as our pump selection software WinPump are available. Speed 1450 rpm Speed 2900 rpm 4

6 Technical details Constuction Multi-stage ring section pump of robust construction with extra large shaft section for vibration-free running. For high output pressures additional axial thrust balancing is provided by a balancing piston mounted on pump shaft. All wearing parts are renewable without additional work on the casing parts. Shaft sealing either with gland packing or mechanical seal. Bearing housings are protected against the ingress of spray water by means of lip seals. Under difficult suction conditions (low NPSH-available), the pump can be provided with an axial inlet for cavitation-reducing flow entry pattern into the first stage impeller. Impellers At least two types of impellers with matching diffuser are available for each pump frame. Therefore operation within the range of optimum efficiency is possible for the required output conditions. If an abrasive medium is being pumped, the slip face and hub section of the impeller can be protected by renewable rings / bushes in wear resistant materials. Shaft and bearings In all the pumps the shaft is protected against wear and corrosion over its entire length by shaft wear sleeves, especially in the area of the shaft seal (gland packing or mechanical seal) and the sleeve bearings in arrangement AX and S. In case of pumps in arrangement A1 and A3, the shaft is mounted outside the pump body in grease lubricated ball bearings (a radial deep groove ball bearing on the suction side and a fixed bearing with paired angular contact ball bearings on the delivery side). On arrangement A2, AX and S, the shaft is carried in a shielded sleeve bearing lubricated by the pumped medium on the suction side and, on the delivery side, by grease lubricated angular contact ball bearings. All rolling bearings are protected by lip seals. Shaft sealing In the standard version the shaft is sealed by gland packing. The packing rings form a seal with a renewable shaft sleeve which protects the shaft against wear. Mechanical seals acc. to DIN can be fitted (also retro-fitted). According to requirements following mechanical seals may be used: single acting unbalanced mechanical seal single acting balanced mechanical seal double acting mechanical seal in tandem arrangement double acting mechanical seal in back-to-back arrangement Mechanical seals are always mounted on a shaft wear sleeve in stainless steel. Axial thrust compensation In pumps with a small number of stages the ball bearings (fixed bearings) absorb the axial thrust. In pumps with a larger number of stages, the axial thrust is equalised by means of a balancing piston mounted on the shaft in the area of the delivery housing. Pump type Balance piston as per number of stages at speed Slip faces In order to prevent wear in the slip face and hub area as far as possible interchangeable wear-resisting casing rings and neck bushes are fitted in the housing. The slip faces of the impellers can also be protected by renewable slip rings. Coupling Connection between pump and IEC standard motor by flexible coupling N-Eupex, type B. Drive In case of horizontal arrangement by IEC standard motor in form B3 with supporting feet. In case of vertical arrangement by IEC standard motor in form V1, with flange connection according to DIN
